\[\boxed{\mathbf{534\ (534).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ \frac{2}{3}x = 1\]

\[x = 1\ :\frac{2}{3}\]

\[x = 1 \cdot \frac{3}{2}\]

\[x = \frac{3}{2}\]

\[x = 1\frac{1}{2}\]

\[Ответ:1\frac{1}{2}.\]

\[2)\ 5x = \frac{1}{6}\]

\[x = \frac{1}{6}\ :5\]

\[x = \frac{1}{6} \cdot \frac{1}{5}\]

\[x = \frac{1}{6 \cdot 5}\]

\[x = \frac{1}{30}\]

\[Ответ:\ \frac{1}{30}.\]

\[3)\ 4x = \frac{1}{4}\]

\[x = \frac{1}{4}\ :4\]

\[x = \frac{1}{4} \cdot \frac{1}{4}\]

\[x = \frac{1}{4 \cdot 4}\]

\[x = \frac{1}{16}\]

\[Ответ:\ \frac{1}{16}.\]

\[4)\ 7x = 20\]

\[x = 20\ :7\]

\[x = \frac{20}{7}\]

\[x = 2\frac{6}{7}\]

\[Ответ:2\frac{6}{7}.\]
